MEASURlNG-FAUCET.

' SPECIFICATION forming part of Letters Patent No. 506,502, datedOctober 10, 1893.

Application filed Septemher 3, 1392. Serial No. 444,954. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. HESS, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Measuring-Faucets, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a measuring faucet-,jthe parts of which are ofsimple,inexpensive and practical construction, as will be hereinafterset forth.

Figures 1 and 2 represent vertical sections of a measuring faucetembodying my invention, the plug thereof being in diiferent positions.Figs. 3, 4 and 5 represent horizontal sections respectively on line x,00, y, y, and

z, .2, Fig. 1.

Similar letters of reference-indicate corresponding parts in the severalfigures.

Referring to the drawings:A designates the measuring chamber of afaucet, B the rotary plug, (J the seat for said plug, and .D

the supply nozzlewhich is to be insertedinto.

a barrel, keg, tank or other receptacle from which fluid is to be drawn.7

In the plug B are the ainvents E and F, the supply port- G, anddischarge ports H and 'J. In the seat 0 is the air vent K, the supplyport L, and the discharge port M. The ventE is of angular form, andextends in horizontal direction. The vent F joins the angle of the ventE, and extends vertically therefrom, so as to open into the atmosphere.Either limb ofthe vent F is adapted to be placed in communication withthe vent K of the seat 0. The port G extends horizontally through theplug B, and is adapted to be placed in and out of communication with theport Lof the seat 0. The port H and port J, extend respectively at anangle to each other in horizontal and vertical directions, the port Hbeing adapted to be placed in and out of communication with the port Mof the seatO.

, The operation isas follows:-\Vhen the plug is turned to the positionshown in Figs. 1, 3, 4 and 5, the fluid entering the bore of the nozzleD, flows through the port Gand port L, and so enters the chamber A, itbeing noticed that the port H is closed to the port M, where by thefluid fills the chamber A. As one of the vents E is in communicationwith the K, thus preserving a communication with the atmosphere, whileat the same time, the port G is closed to the bore of the nozzle D, andto the port L, whereby the supply of fluid to the chamber A, immediatelyceases. Simultaneously therewith, the port M of the seat is placed incommunication with the port H of the plug, and so the fluid dischargesfromthe chamber A, through said ports M, H, into the port J, by whichlatter, it is directed into a receptacle provided for the purpose, itbeing noticed that as the vent F, E, is open to the atmosphere, thechamber A may be supplied with air to permit the contents to dischargethrough the ports M, H, J, as has been stated.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A measuring faucet having an air vent in its plug'with horizontalpassages at angles to each other, and a communicating vertical passageleading to the atmosphere, both of said horizontal passages beingadapted to communicate with a vent in the body of the faucet,substantially as described.

2. A measuring faucet consisting ofa body A, with plug B, said bodyhaving an air vent K, a discharge port L, and a waste port M, and saidplug having a discharge port G horizontal vents E with a verticalcommunicating [vent F, and waste port J, one of said vents Ecommunicating with said ventK, both at the opening and closing of theport G, said parts being combined substantially as described.
